Aubrey,
Thank you for your response; this is certainly very clear to me. I understand the encryption and security measures of VW. I went to an official dealer and I'm going to buy a completely new one, and I have also placed an order. This cost me 500 euros, 400 for the car key and 100 euros for reprogramming because the technician could do it in the car; it's not possible remotely.
Well, through a Dutch second-hand, I found the exact key 3V0959752P AIF, also mentioned for 5 euros. I also ordered a new ID48 Transponder Chip, which cost me 1 euro.
Now, my question is, is it not possible to clone? If yes, do you know a good company or professional who can do this, or is it still necessary to go through the official dealer for programming? The second-hand order is still to be delivered by DHL, and the ID48s are also on their way via AliExpress.
I'm trying; if this works out for me, I'll have 2 new keys and 1 official key for 7 euros. Pretty nice, right?
Also, thanks to Yogi-Bear for your response - but my question was completely different, by the way.
